lVlOLD FOR FORMATION OF TICKET-RACKS.

SPECIFICATION forming part of Letters Patent No. 537,470, dated April16, 1895. Application filed November 8, 1894. Serial No. 528 ,207- (Nemodel.)

To all whom it may concern.-

Be it known that I, WILLIAM MANN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Molds for the Formationof Ticket-Racks; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

It is the common practice to arrange theater tickets for sale by the useof a rack having apertures arranged substantially to cor respond withthe diagram of the auditorium. Such racks have been made of wood but areexceedingly expensive and very apt to warp and crack. I find that a slabformed of a plastic material, such as plaster of paris, makes a muchbetter rack than wood, and my invention relates to a mold for the readyand economical formation of such a slab, and consists of a multiplenumber of strips or blocks transversely slotted to removably hold platesor forms of the size of the desired aperture whereby a bed may be madeupon which the soft material may be poured, the plates being drawn outthrough it as it sets.

Certain additional details of the invention will be hereinafterspecifically pointed out. V

Figure 1, is a plan view partly broken away showing the cement slab orrack in process of molding and the form of the mold. Fig. 2, is asectional view on the line 2-2 of Fig. 1. Fig. 3, is a perspective ofthe rack ready for use. Fig. 4, is a sectional view on the line 4-4 ofFig. 3. Figs. 5, 6 and 7 are details of the molding appliances.

The rack A is preferably about one inch in thickness and is providedwith a number of apertures or slots a, passing entirely through it andadapted to receive the tickets to be used in connection with it. Thisrack is mounted in a suitable case B, having a back 12, space being leftbetween the rack A, and the back I), so that the ticket H, may beinserted within one of the slots at, to such depth that only as much ofits outer end will project as may be necessary to designate the seat towhich it applies. The rack A, is held within the case by means of thestop block b, behind it and the beading 11 in front of it.

The ticket slots a, may be arranged to conform approximately to thearrangement of the seats in the auditorium of the theater as indicatedin Fig. 3.

The appliances for molding the rack or slab A, consists of a multiplenumber of strips E, having transverse slots 2, adapted to receive metalplates F, whose thickness and width correspond with the thickness andlength respectively of the slots at. The bars for holding these metalplates F, may be curved as shown at E, for the purpose of providing thecurved rows of seats indicated in the upper portion of Fig. 3. Thestrips E, E, are arranged to correspond with the diagram of the house,one strip being used for each row of seats, and are spaced apart by thebars G, G, of exactly the same thickness as the strips so that whenthestrips and bars are brought together an even surface is formed.

The strips and bars having been suitably arranged, a case or chase D, isplaced about them, its depth being sufficient to retain enough of theplastic material to form a slab of the desired thickness. The plates F,are now set within the slots 6, the number used in connection with thestrips being the same as the number of seats indicated in the diagram ofthe theater. These strips are of such length that they will project to agreater distance from the strips E, E, than the thickness of the slab tobe formed.

The plates F, having been properly arranged, the plastic material isplaced upon the mold thus formed, care being taken to spread ittogiveapproximately an even thickness. Before it has become thoroughlyhardened, the plates F, are drawn leaving the slots a, perfectly formed.When the plastic material has become thoroughly hardened the slab A, isremoved from the chase D, and placed within the case B, the surfacewhich was next to the body of the mold being outward, and the rack isnow ready for use as soon as it is completely dry and after having beensuitably decorated with paint or stain.

I am aware that plastic material has here- ICO tofore been molded withapertures, by means of removable plates or forms and I do not broadlyclaim such construction.

I claim as my invention 1. In a mold for forming plastic ticket racks,the combination with the transversely slotted strips E, of the plates F,adapted to the slots and to project upwardly from the strips, and theframe D, adapted to surround a form composed of a multiple number ofstrips and to project above the strips, substantially as described andfor the purpose specified.

2. In a mold for forming apertured ticket racks of plastic material, thecombination with a multiple number of transversely slot- WILLIAM MANN.
